Martial Arts Comedy: The Echoing Secret

[Style]
Poetic Xianxia deadpan twist comedy, cinematic high-definition texture, using classical Chinese architectural spatial composition, restrained performance, cold mountain mist, warm evening rim light, low-saturation jade green and ivory white tones, fine film grain; reverse through 'buildup - misleading - off-screen strike' sound narrative. Designed for Seedance 2.0's character locking, multi-shot continuous generation, and synchronized spatial audio. Only two visible characters, pure ancient Chinese world with no modern elements.
[Characters]
Character A: Strictly locked using @Image 1, a 25-30 year old East Asian Sword Immortal Senior Sister, oval face, fair skin, dark almond eyes, black long hair with jade hairpin, tall and slender, wearing white embroidered silk Hanfu.
Character B: Strictly locked using @Image 2, a 20-25 year old East Asian Junior Sister, round face, braided black hair, small stature, wearing cyan-green linen Hanfu.
[Shot 1 | 0-3s | Low-angle panoramic tracking shot]
A quiet sect platform above a sea of clouds with stone railings, echo walls, nine bronze bells, and ancient pines. Senior Sister stands next to Junior Sister, looking around cautiously with a confident expression of preparing to share a secret.
[Shot 2 | 3-6s | Medium shot of both characters]
Senior Sister forms a sound transmission seal with her fingers and whispers: 'Tell you a secret, Master stole three pieces of osmanthus cake last night.' A thin blue sound wave flies precisely to Junior Sister's ear; she wide-eyed, covering her mouth to suppress laughter.
[Shot 3 | 6-10s | Close-up reveal to extreme close-up]
The sound wave doesn't stop, hits the echo wall, and bounces through the nine bronze bells, broadcasting the secret across the valley: 'Master stole three pieces of osmanthus cake—'. Bells vibrate, birds fly off the roofs. A cough from the main hall asks calmly: 'Who ate the fourth piece?' Both characters freeze. Extreme close-up on Senior Sister's twitching eyebrow and Junior Sister's puffed cheeks, ending with a soft gulp of guilt.
[Technical Requirements] 10 seconds total, 16:9 aspect ratio, three clear shots, native Mandarin dialogue, accurate lip-sync, directional sound movement, stable character and costume identity, natural movement of mist and silk, no subtitles.

【镜头 1｜0-3s｜低角度全景横向跟拍】
云海之上的安静宗门石台，石栏、古老回音壁、九只悬挂青铜铃、盘曲古松、随风飘动的祈福布条和远处瓦顶殿宇共同建立清楚稳定的空间关系。同一个穿白色刺绣真丝汉服的剑仙师姐站在同一个青衣小师妹身旁，谨慎环顾四周，露出准备分享秘密的自信神情；山风轻轻带动两人的头发、衣袖、布条和薄雾。

【镜头 2｜3-6s｜双人中景】
同一个剑仙师姐抬起两指，在嘴边结出一个小型传音法印，压低声音说道：“告诉你一个秘密，师父昨夜偷吃了三块桂花糕。” 一道纤细的淡蓝色声波精准飞向同一个小师妹的耳边；她瞬间瞪大眼睛，抬手捂住嘴，努力忍住笑。

【镜头 3｜6-10s｜近景跟随揭晓转极近特写】
同一道声波没有及时停下，越过小师妹撞上同一面古老回音壁，随后依次反弹穿过同样九只青铜铃，把刚才的悄悄话以巨大回声传遍整座山谷：“师父昨夜偷吃了三块桂花糕 ——” 九只青铜铃按顺序震动，远处殿宇屋顶上的鸟群受惊飞散。主殿方向传来一位不可见老者的一声轻咳，随后平静问道：“第四块，是谁吃的？” 同一个剑仙师姐和同一个小师妹同时僵住。极近特写：剑仙师姐举起的两根手指缓慢蜷缩，一侧眉毛轻轻抽动，默默转眼看向小师妹；小师妹的两边脸颊明显鼓起。最后以一声极轻、充满心虚感的吞咽声结束。
